Soft Sensor Modeling of Marine Lipase Fermentation Process Based on Bayesian--《Measurement & Control Technology》2015年11期
ZHU Xiang-lin;YUE Hai-dong;SUN Mi;School of Electrical and Information Engineering,Jiangsu University;Yellow Sea Fisheries Research Institute,Chinese Academy of Fishery Sciences;In order to solve the problem that crucial biological variables(such as biomass concentration,glucose concentration and so on) in low-temperature alkaline lipase are difficult to online real-time detect,a modeling method based on the weighted least squares support vector machine(WLS-SVM) within the Bayesian evidence framework is proposed.First,nonlinear modeling of biological variables is analyzed,and the auxiliary variables of the soft sensor model are determined.Then,training samples are used to train the least squares support vector machine,during the training process,the models of the optimal weight vectors,the optimal regularization parameter and the optimal kernel parameter can be found through three-layer Bayesian evidence.To improve the robustness of the model,the weighted coefficients are calculated according to the error variables.The WLS-SVM model which can predict biological parameters accurately in the process of fermentation is established.Comparison of the conventional LS-SVM model in test simulation,results show that the WLS-SVM based on Bayesian inference has features of high prediction precision,good generalization ability,and rapid calculation. 【Fund】: 国家\"863”计划项目(2011AA09070301);;吉林省重大科技攻关专项(20140203005SF) 【CateGory Index】: TQ925.6;TP18 Download(CAJ format) Download(PDF format) CAJViewer7.0 supports all the CNKI file formats; AdobeReader only supports the PDF format.
